2. An apparatus for performing cryoscopy.
cryoscopy, cryoscopic, cryoscopical, kryoscopy
1. The determination of the freezing point of a fluid, usually blood or urine, compared with that of distilled water.
2. Examination of liquids, based on the principle that the freezing point of solutions varies according to the amount and the nature of the substance contained in them in solution. Also algoscopy.
A cryogenic semiconductor device that, after ionization, can act as a three-terminal switch, a pulse amplifier, an oscillator, or a unipolar transistor.
cryosorption, cryosorb
The process of capturing a gas on or in a material that has a very large surface and that has been cooled to a very low temperature.

The weak attractive force between the gas and surface is enhanced by the low temperature.

Spasm produced by cold.
The region, or portion, of the earth’s surface that is characteristically covered by snow and ice and so frozen throughout the year.

Studies of the extent and status of the cryosphere can provide insights into the present and the past climate changes.

cryostat (s) (noun), cryostats (pl)
1. A device by which a certain temperature can be maintained at a very low level: The specimen was put in a cryostat which cooled it down considerably.
2. A freezing chamber: The students were introduced to the cryostat where they would be cutting microscopically fine parts of tissues with a microtome.
One who uses freezing temperature to destroy diseased tissue.
cryosurgery, cryosurgical
1. An operation using freezing temperature (achieved by liquid nitrogen or carbon dioxide) to destroy diseased tissue.
